<p class="MsoNormal">I am unable to replicate your issue in ParaView 5.4.1. When I loaded your data and showed the broken_joint data in wireframe, I was clearly able to see the lines of broken_joint over the polygons of basic. (See the attached image.)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The problem you are getting is likely caused by z-buffer fighting in the rendering. This happens when two objects are the exact same distance from the viewer, as I believe is the case in your data. Wanting to draw lines on top of polygons
is common enough that there are some corrections to help the rendering determine what to draw in front. Perhaps by changing the settings on resolving coincident topology will resolve your issue. You can find them by opening the ParaView settings dialog (Edit
→ Settings), clicking on the Render View tab, and turning on the advanced options. The options you are looking for are “Resolve Coincident Topology,†“Polygon Offset Parametersâ€, and “Z Shift.â€<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Another, possibly easier, solution it to simply move the lines of the broken_joint data closer to the camera. Click the broken_joint object and add the Transform filter. Change the Translate parameter to 0, 0, 1 and apply. That should shift
the wireframe forward enough to see it properly.<o:p></o:p></p>

<p class="MsoNormal">Hi,<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">I use ParaView to visualize data of our simulations using the Unstructured Grid data format. Up until ParaView 4.x everything worked fine: we typically visualize one set of data files as Surfaces and another
as Wireframe. The Wireframe dataset refers to "fracture lines" in our simulations.
<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">See below how the simulation looked like in PV version 4.x. You could clearly see the line around the boundaries of the model.<br>

</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">However, in PV 5.x the lines are not fully visualized as if they're hidden below the other data object:<br>

</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">I've tried a few versions of 5.x but they all behave similarly.
<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">Does anyone know what might be going on here? Is this a bug / removed featured from the new version or should I do something different with 5.x? I've noticed that this issue does not happen consistently. I've
seen the issue on both Linux Mint 17.3 (64 bit) and Ubuntu <o:p></o:p></p>
</div>
<p class="MsoNormal">I've attached two example VTU files. Please visualize the second file as Wireframe (_broken_joint). Below are two large VTU files.
